The switch to the left of the instrument panel could be for switching between sending units in the in-cab tank and an auxiliary tank. Is there any other evidence of an auxiliary tank? Tank switch valve on the floor of the cab, an extra tank or two, RPO NL2 on the option sheet on the glove box door?
